29 Οκτ 2024 · The SkyCiv Stress-Strain Calculator allows you to calculate stress-strain values for non-linear RC design parameters as per the theory proposed by Mander et al. (1988). This approach is applicable for confined concrete with both circular and rectangular-shaped transverse reinforcement.
Stress-Strain Calculator and Plotted Curve Approximation using Ramberg-Osgood Equation: The Ramberg–Osgood equation is used to approximate the non linear relationship between stress and strain, the stress–strain curve in materials near their yield points.
Stress strain curve of concrete is a graphical representation of concrete behavior under load. It is produced by plotting concrete compress strain at various interval of concrete compressive loading (stress).

The slope of the initial straight portion of the curve gives the elastic modulus or modulus of elasticity (E) of concrete. This indicates the material’s stiffness – its resistance to deformation. The stress-strain diagram also shows the yield point, ultimate strength, and rupture point of concrete. forum.ansys.com.
Moment curvature analysis is a method to accurately determine the load-deformation behavior of a concrete section using nonlinear material stress-strain relationships.
